The girls’ mother, Amanda Hawkins, 20, was indicted in June and is slated to stand trial in March on two charges of injury to a child and two charges of endangering a child, court records show.

Franke’s lawyer, Joe D. Gonzales, said Monday that his client was initially charged more than a month ago as a juvenile.

The case was referred Friday for prosecution in adult court by state District Judge Keith Williams.

If indicted, Franke, now 17, faces prosecution as an adult on two charges of manslaughter, two charges of injury to a child and two charges of child abandonment. He was booked Saturday at the Kerr County Jail, where his combined bonds total $310,000.
